 exceeded by few of the Insect-Tribes. Green, gold, 

 purple, scarlet, and similar brilliant hues frequently 

 adorn them, as in the Coleoptera, their assemblage, 

 and bold contrasts being very similar in both Orders. 

 Many of these insects live chiefly in the water,

 drawing nourishment in this manner; the mouth
